Accident Details
During an approach to a 2,875-foot mountaintop runway, the airplane banked sharply left and dropped down the mountainside just prior to reaching the runway 14 threshold. The airplane then collided with trees and terrain and burst into flames. The pilot had reported turbulence prior to conducting the approach.
Witness Observations
Several witnesses outside on the decks of a country club and a restaurant adjacent to the mountaintop runway observed the airplane. The airplane made a low pass down runway 14, then entered the traffic pattern. Witnesses reported seeing the airplane on a low, flat final approach to runway 14 with its gear and flaps down. One witness stated the airplane appeared as if it was going to land directly on the numbers, but just prior to reaching the end of the runway, it suddenly banked left and dropped down the mountainside out of view.
